IMAGE PROCESSING DEVICE AND IMAGE PROCESSING METHOD

摘要

Provided is an image processing device which reduces the influence to output image data from a compression error of image data generated in the previous frame. An image processing device generates a compression error prediction value (ERR) on the basis of input image data (DI), generates substitute image data (DIA) of the input image data (DI) on the basis of the appearance tendency of the compression error, selects the input image data (DI) or the substitute image data (DIA) as current image data (DC) on the basis of the compression error prediction value (ERR), generates subsequent state image data (DP) on the basis of the current image data (DC) and state image data (DR), generates compressed state image data (DPC) by compressing the subsequent state image data (DP), stores the compressed state image data in a frame memory (18), generates the state image data (DR) by reading the compressed state image data (DPC) from the frame memory (18) and expanding, and generates output image data (DQ) on the basis of the current image data (DC) and the state image data (DR).
